Generally, the PNP transistor can replace NPN transistors in most electronic circuits, the only difference is the polarities of the voltages, and the directions of the current flow. PNP transistors can also be used as switching devices and an example of a PNP transistor switch is shown below. In the next tutorial about … See more Basically, in this type of transistor construction the two diodes are reversed with respect to the NPN type giving a Positive-Negative-Positive type of configuration, with the … See more Also, all the polarities for a PNP transistor are reversed which means that it sinks current into its Base as opposed to the NPN transistor which … See more The construction and terminal voltages for an NPN transistor are shown above. The PNP Transistor has very similar characteristics to their NPN bipolar cousins, except that … See more (Note: Arrow defines the emitter and conventional current flow, in for a PNP transistor.) We can see that the fundamental differences between a NPN Transistor and a PNP Transistor is the proper biasing of the … See more WebJan 4, 2024 · A PNP transistor is a dual of an NPN transistor, and so they are complementary to each other. Their bias voltages and currents are in opposite directions. …

WebMar 21, 2024 · By using a PNP, its collector voltage must be less than its emitter voltage. As we're also using a bipolar power supply, we can eliminate the need for the final output coupling capacitor. All we need to do is set up the resistor values such that the drop across R C 2 is the same as V E E. WebExample: D.C. Analysis of a BJT Circuit. Example: An Analysis of a pnp BJT Circuit.
